Morphological Description and Evaluation of Six Newly- Introduced Grape Cultivars under Egyptian Conditions.
Six newly-introduced grape cultivars nemely Arra 30, Arra 29, Arra 13, Arra 24, Arra 27, and Arra 15, were investigated in three successive seasons ( 2014, 2015 & 2016) for description and evaluation under Egyptian conditions.The cultivars were grown in a private vineyard situated at Birqash region – Giza governorate, Egypt. Vines were planted in sandy soil spaced 3X2 meters apart and irrigated by drip irrigation system and supported by Gable system. The study included time of bud burst, young shoots, young leaves, shoot, and time of bloom, flower, mature leaf, beside determining time of ripening, Bunch, berry, Tss, Acidity, Tss / acid ratio, and seed formation.The studied cultivars were characterized by good vegetative growth and good fruit quality. The tips of the studied cultivars were fully open Color of upper side of blade for the young leaf was green with anthocyanin spots in Arra 30, Arra 29, and Arra 24, but dark copper- red in Arra 13, and Arra 27, while light copper-red in Arra 15. The internode was long, thick and number of consecutive tendrils were less than three in all cultivars. The tip of tendril was tri-fid in Arra 29 & 15 while di-fid in Arra 13, it was di-tri in Arra 30,Arra 24 and Arra 27. The length of tendril was very long in Arra 30, Arra 29, and Arra15 and long in Arra 13, Arra 24 and Arra 27. Entire of cultivars had flowers with male and female parts fully stamens and developed gynoecium in all studied cultivars. The shape of blade was circular in Arra 27, and Arra 15, and pentagonal in the other cultivars. Depth of upper lateral sinuses was shallow in Arra 29 , Arra 27 and Arra 15 while was very deep in Arra 30 , Arra 13, and Arra 24. Arrangement of lobes of upper lateral sinuses was closed in Arra 27, and Arra 15, but slightly overlapped in the others . Petiole sinus slightly open at Arra 30, Arra 24, and Arra 15, wheaser half open in Arra 13, and Arra 27, and wide open in Arra 29. Petiole shape was u- shape in Arra 29, , Arra 13, and Arra 24, while it was v-u shape at the others. Length of petiole as compared to middle vein was moderately shorter as well as sinus limited by veins which was constantly absent in all cultivars. Anthocyanin pigment of main veins on the upper side of blades was strong in Arra 30, very low in Arra 29, low in Arra 24, and absent in the others. Yield / Feedan data showed that consequently for the studies cultivars were Arra 15> Arra 29 > Arra 30> Arra 27> Arra 24> Arra 13.Bunch weight of all studied cultivars was big, bunch shape was shouldered in Arra 30, Arra 27, and Arra 15, conical in Arra 29, and Arra 13, while winged in Arra 24. Berry shape in Arra 30, Arra 13, and Arra 15, was cylindrical and obtuse ovoid in Arra 29, And Arra 27, while broad ellipsoid in Arra 24. Berry color in Arra 30, and Arra 15, light green, while bright red in Arra 29, reddish black in Arra 24, dark red violet in Arra 13, and blue black in Arra 27. Formation of seeds was absent in Arra 29 and Arra 15, but rudimentary in the others (All cultivars seedless). Arra 24, ripened in the last week of May, Arra 30, and Arra 29, in the second week of June, Arra 13, in the third week of June while Arra 27, and Arra 15, in the third week of July. Woody shoot for the studied cultivar was yellowish brown expect Arra 13, which was dark brown and the relief surface for all cultivars was striate. Bud fertility lengthwise the cane increased gradually from the basal buds to middle buds than decreased gradually towards the distal buds, except with the variety Arra 13, as it increased at the basal buds then steadiness at middle and distal bud. It can be recommended to prune Arra 30, Arra 29, Arra 27, Arra 24, and Arra 15, to cane pruning system ( 8-10 buds / cane ) while Arra 13, to be pruned according to the spur pruning system ( 2 buds).

Effect of Boron Level and Time of Application on Yield and Quality of Sugar Beet
Two field experiments were carried out in 2015/2016 and 2016/2017 seasons at Sakha Agricultural Research Station, Kafrelsheikh Governorate (latitude of 31.100 N and longitude 30.930 E, at an elevation of 14 m above sea level) to find out to the appropriate fertilization level of boron and its application time on growth, yield and quality of sugar beet crop. The present work included twelve treatments represent the combinations of four levels of boron (zero, 50, 100 and 150 ppm) and three application times of 30, 60 and 90 days after sowing. Boron was sprayed on beets as a boric acid 17% boron. The experimental design was strip plot with four replicates, where vertical plots were occupied with boron levels, while the horizontal plots were devoted to the three application times. The results showed that increasing boron application to 100 and/or 150 ppm resulted in higher values of root diameter, root fresh weight/plant, foliage fresh weight/plant, sucrose%, sugar extractable% and quality index as well as root, top and sugar yields/fed, at harvesting time in both seasons, whilst sugar lost to molasses%, Na and K contents significantly decreased.It was found that boron application time had a significant effect on root diameter, root, and foliage fresh weight/plant as well as top yield/fed of sugar beet in both seasons, as well as sugar yield/fed in the 1st one, where the application time of 90 days achieved the highest values of the mentioned traits. However, root impurities (Na, K and α-amino-N) and sugar lost to molasses% were insignificantly affected by the time of boron application. The interaction between boron concentration and its application time significantly affected root fresh weight/plant in both seasons and root yield/fed in the 1st season only. The combination of (150 ppm boron fertilization at 90 days of sowing) attained the highest values of root fresh weight (9, 796 g and 1, 769 g) in the two seasons respectively, as well as the maximum root yield (60, 22 ton/fed) in the first season only. Under conditions of the present work, fertilizing beets with 100 and/or 150 ppm boron as foliar application at 90 days from sowing can be recommended to get the highest root and sugar yields/fed.

Two field experiments were conducted at the Experimental Farm of Rice Research Department (R.R.D.), Sakha, Kafrelsheikh, Egypt during 2015 and 2016 seasons. In order to examine the impact of potassium silicate compound as foliar application on the growth, yield and grains quality of Giza 179 rice cultivar. A randomized complete block design (R.C.B.D.) with four replications was used in the two seasons. Foliar applications of potassium silicate, at the rate of control (without potassium silicate), 0.5%, 1.0%, 1.5% and 2.0 % potassium silicate were sprayed twice with the same concentration at 15 and 30 days after transplanting. The studied characters were; chlorophyll content in flag leaf, leaf area index, dry matter accumulation, plant height, no. of tillers per m2, no. of panicles per m2, panicle length cm, panicle weight g, total no. of grains per panicle, thousand grain weight, grain yield ton/ha, percentages of hulling, milling and head rice and silicon content in stems, grains and straw .The results showed that application of potassium silicate caused an increased in growth characters, yield, yield attributes and grains quality of Giza 179 rice cultivar. Potassium silicate at the rate of 1,0% produced the maximum values of chlorophyll content in flag leaf, leaf area index, dry matter accumulation, plant height, number of tillers/m2, number of panicles/m2, length of panicle (cm), weight of panicle (g), grain yield(ton/ha), as well as, hulling, milling, head rice percentages of Giza 179 rice cultivar, while sprayed Potassium silicate at the rate of 1.5 % resulted the maximum total number of grains/panicle and the rate of 2.0% produced the maximum silicon content in stems, grains and straw. All the other parameters showed overlapping results of different potassium silicate levels. According to the previous results, it could be concluded that using potassium silicate as foliar application twice with the same concentration 1.0% at 15 and 30 days after transplanting was the best treatment for improving growth and obtaining the greatest grain yield besides the grains quality of Giza 179 rice cultivar.

Response of Egyptian Hybrid Rice One Cultivar to Zinc Sulphate, Potassium Sulphate and Magnesium Silicate as Foliar Application.
The two field experiments were conducted during 2015 and 2016 seasons at the Experimental Farm of Rice Research Department (RRD), Sakha, Kafrelsheikh, Egypt. In order to examine the response of Egyptian hybrid rice one cultivar to foliar application of zinc sulphate, potassium sulphate and magnesium silicate. A randomized complete block design (R.C.B.D.) with four replications was used in the two seasons. The used treatments of foliar applications of zinc sulphate, potassium sulphate and magnesium silicate were used as follows: (T1), control (without any application of the three tested compounds); (T2), Zinc sulphate; (T3), potassium sulphate; (T4), magnesium silicate; (T5), Zinc sulphate + potassium sulphate; (T6),Zinc sulphate + magnesium silicate; (T7), potassium sulphate + magnesium silicate and (T8), Zinc sulphate + potassium sulphate + magnesium silicate. The foliar applications treatments were applied twice with the same concentration 2% at 15 and 30 days after transplanting. The studied characters were; plant height (cm), leaf area index, dry matter accumulation (g/m2), chlorophyll content in flag leaf ( SPAD-Value), number of tillers per m2, number of panicles per m2, number of grains per panicle, panicle weight (g), filled grain percentage, thousand grain weight, grain yield(ton/ha) and hulling, milling, head rice and milled grain protein percentages. The results showed that combined foliar application of the three tested compounds caused an increased in the previous studied growth characters, yield, yield attributes and grain quality of the Egyptian hybrid rice one cultivar. While, control treatment (without spraying) resulted maximum thousand grain weight (g) without significant differences between control and combined application of the three tested compounds in this criteria. All the other parameters showed overlapping results of different foliar application treatments. According to the previous results, it could be concluded and that: Using foliar application of zinc sulphate, potassium sulphate and magnesium silicate twice with the same concentration 2.0% at (15 and 30 days after transplanting) was the best treatment for obtaining the greatest grain yield besides improving growth and the grain quality of Egyptian hybrid rice one cultivar. Using of the previous fertilizer compounds as foliar spray saved about more than two thirds from the amount of zinc sulphate and potassium sulphate if applied as basal application which is a result to application of magnesium silicate which caused integration with zinc sulphate and potassium sulphate.

Response of some Sorghum (Sorghum bicolor, L. Moench) Cultivars to Foliar Spraying of Riboflavin Growth, Grain Yield and Proline Content
Recently, many environmental fluctuations affecting sorghum production such water shortage, increases in temperatures, soil salinization, drought, improper use of soil and hyper-fertilization. There were Many studies attempted to solve these problems. Thus, this study is conducted to investigate the effect of foliar spraying riboflavin at different concentration on growth traits, proline content in the plant, grain yield and yield components of three sorghum cultivars. Results revealed that Rabih cv. was significantly superior in most studied traits, such as plant height, leaf area, leaf area index, flag leaf area, leaves proline content and number of grains per head. This increment in the traits mentioned previously reflected positively on grain yield per unit area in both seasons as it produced 7.05 and 7.12 ton/ha, respectively. Foliar application of riboflavine improved most of vegetative growth traits including plant height and leaf area, while it reduced the proline content in plant which make it able to avoid stress during its life time. This in turn increased the grain yield and its components. In both season, foliar application of riboflavin at the conc. of 300 mg l-1 gave the highest grain yield amounted to 7.29 and 7.22 ton h-1, respectively. There were significant interaction between cultivars and riboflavin conc. in most traits. It can be concluded from this study that high grain yield can be obtained by sowing Rabih cv. and spraying with riboflavin at concentration of 300 mg L-1

Integrated Impact of Organic and Inorganic Fertilizers on Growth, Yield of Maize (Zea mays l.) and Soil Properties under Upper Egypt Conditions
A field study was carried out during the two consecutive summer seasons of 2015 and 2016 at the Experimental Farm, Faculty of Agriculture, Al-Azahar University, Assiut Governorate located 375 km south of Cairo, Egypt (27° 12- 16.67= N latitude and 31° 09- 36.86= E longitude). The experiment aims to study the effect of useing different fertilizers including (NPK), ureaform (UF), compost (C), Sheep manure (S), humic acid (HA), and yeast extract (YE) on growth, productivity and quality of Maize yield (var., Hi-Tech 1100). The experiment was a Randomized complete Block design (RCBD) with three replicates.The treatments were six: (T1) Check treatment full recommended NPK (Control), (T2) = (CS + UF), (T3) = (YE + UF), (T4) = (HA + UF), (T5) = (CS + YE) and (T6) = (CS + HA). In both seasons, the combination of 10 tons fed-1 of compost and sheep manure plus 50 kg fed-1 of ureaform (T2) resulted in the highest growth, yield and yield components and quality of maize as comparedto the others treatments. The effect of different combination from the used fertilizers could be arranged in the following descending order T2 > T6 > T5 > T4 > T1 >T3. Treatment (T2) gave the highest grain yield (3494 and 3676 kg fed-1) with an increase of (29.31 and 21.84%) as compared to T3 (2702 and 3017 kg fed-1) during 1st and 2nd seasons, respectively. The NPK maize grain content as affected by different combination could be arranged in the following descending order T3 < T1 < T4 < T5 < T6 < T2. Also, compost and sheep manure addition improved soil properties since they increased organic matter content and decreased soil reaction (pH). Finally, it could be concluded that the integration of organic and inorganic fertilizers was better than using organic or inorganic fertilizer separately. Using the high amount of organic fertilizers (10 ton fed-1 CS) with ureaform (50 kg fed-1 UF) was the best treatment for producing high quality and increasing yield of maize crop under Upper Egypt conditions in Assiut.

Impact of Magnetized Water Irrigation, Soil Mineral Fertilization and Foliar Spraying with Nanomaterial on Potato Plants.
The present work was conducted at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, Egypt, during the two successive winter (critucal) cultivation of 2015/2016 and 2016/2017 to investigate the impact of irrigation water (normal water - magnetized water), levels of soil mineral fertilizers and foliar spraying with nano-material (without - Lithovit) as well as their interactions on growth, yield, chemical composition and quality of potato cv. Spunta. Obtained data cleared that irrigation with magnetized water produced the highest significant values of plant growth, chlorophylls, yield, chemical composition and quality parameters except nitrate (NO3) and nitrite (NO2) contents compared to normal water treatments. Meanwhile, fertilized potato plants with 100% NPK from recommended dose gave the maximum values of all studied parameters, except nitrate (NO3) and nitrite (NO2) concentrations which increased compared to other treatments. Moreover, foliar spraying with Lithovit as a nono material increased significantly all studied characters, except nitrate and nitrite, which gave the lowest values in both seasons. It could be recommended that irrigation potato plants with magnetized water, 50% NPK from the recommended dose and foliar spraying with Lithovit (1g/L) in order to maximize productivity, quality parameters and limiting the environmental pollution comparing to plant irrigated with normal water + 100% NPK.

Effect of Sowing Dates and Method on Fodder Beet Productivity under Saline Conditions at Siwa Oasis, Egypt
Fodder Beet is potentially the highest yielding winter forage crops and is high in energy, palatability and digestibility. However, due to susceptibility of fodder beet to salinity at early growth stages and a relatively long growing season, transplanting technique and appropriate sowing date could help to fodder beet production particularly in saline soils. Therefore, two field trials were conducted in Agricultural Experimental Station of Desert Research Center at Tegzerty, Siwa Oasis, Matrouh Governorate, Egypt during 2006/2007 and 2007/2008 growing seasons. These trials were carried out to study the effect of four planting dates i.e. 15 Oct., 30 Oct., 15 Nov., 30 Nov. and two planting methods i.e. direct seeding and transplanting at 45 days on fodder beet productivity under saline conditions.Results indicated that top fresh or dry weights as well as fresh and dry weights of root either per plant or fed. (fed. =0.42 ha.) were decreased with delaying planting dates from 30 Oct. to 30 Nov. in both growing seasons. These reductions may be attributed to reducing length and diameter of roots with delaying planting dates. Whereas, number of harvestable plants/fed., at harvest, was increased with delaying planting date up to the 3rd planting date of 15 Nov. and after then it was decreased with the latest planting date at 30 Nov. Moreover, the percentage of abnormal roots (%) was significantly decreased with delaying planting dates in both growing seasons.Concerning the effect of planting methods, transplanting method markedly increased number of harvestable plants and abnormal root percentage as comparing with the traditional planting method of direct seeding in both growing seasons. Furthermore, top and root fresh or dry weights per plant were decreased with planting fodder beet by transplants. However, fresh or dry fodder beet yield/fed. was increased with planting method of direct seeding in the 1st growing season, but did not reach to a significant level in the 2nd one. These increments may be due to one or more the following reasons; increasing fresh or dry root/plant, top fresh or dry weight/plant, root length and/or root diameter.

Response of Tomato Plants to Irrigation with Magnetized Water and some Foliar Application Treatments under Drip Irrigation System: 1- Vegetative Growth and Chemical Constituents of Leaves.
This experiment was conducted in summer seasons of 2016 and 2017 on tomato plants "6112" hybrid to evaluate tomato plants performance (vegetative growth characteristics and chemical constituents of leaves) in response to irrigation water treatments (magnetized and non-magnetized), foliar applications (chitosan, lithovit, selenium and yeast extract) and their interactions. Results indicated that the highest values of vegetative growth characteristics, i.e., plant height, number of branches, number of leaves, leaf area, fresh and dry weights as well as chemical constituents of leavesas photosynthetic pigments (Chl. a, Chl. b, total Chl. a+b and carotenoids) and leaf minerals content (N, P, K, Ca, Mg, Zn, Mn) were recorded when plants irrigated with magnetized water as compared with plants irrigated with untreated water in both studying seasons. On the other hand, Fe content responded negatively to irrigation with magnetized water.Comparing the effect of foliar applications, all foliar application treatments significantly enhanced vegetative growth parameters, leaf minerals and pigments contents compared to the check treatment. Foliar application of chitosan at 250 ppm is the superior in its effect on all the aforementioned characteristics followed by yeast extract at 10 g/L then lithovit at 1.5 g/L in the two seasons except for Fe content. The best results of both vegetative growth attributes and chemical constituents of leaves were recorded when plants irrigated with magnetized water and sprayed with chitosan at 250 ppm in both seasons. Thus, this treatment could be recommended to improve tomato plants performance under similar conditions of this study.

Evaluation of Using Organic Fertilizer Produced from Biogas Digester under Levels from Mineral Fertilizer Recommendation of Pepper Plants on the Growth, Yield and its Quality
The present study was carried out during the two successive summer seasons of 2016 and 2017, at private farm in Kafr El-Sheik Governorate, under clay loam soil condition using furrow irrigation system. These experiments aimed to evaluate the effect of some combinations between four levels of mineral fertilizer with two types of organic fertilizer produced from biogas digester system (dried and liquid residuals) as well as farmyard manure beside the control treatment on growth, yield and fruit quality of sweet pepper (Capsicum annum L.) cv.California wander as a local famous variety, grown under open field conditions. All organic sources gave rise to a positive effect on plant growth expressed as plant height, number of branches per plant, number of leaves per plant, leaf area per plant, foliage fresh weight and foliage dry weight per plant and increased the percentage of essential macro and micro elements in pepper plant leaves, also produced the highest values of early and total yield and enhancing the fruit quality. Moreover, it increased TSS and ascorbic acid in the fruits as compared with those plants fertilized with mineral NPK alone without organic sources (control). In this concern, dried biogas residual organic fertilizer was the superior source of organic fertilizer, used in this study, which it showed the highest results comparing with the other sources i.e., liquid biogas residual organic fertilizer or farmyard manure. In pepper plants, increasing NPK rate from 25% to 100% of the recommended dose led to an increase in plant vegetative growth. Moreover essential macro and micro elements were increased also in plant leaves. Likewise, early and total yield and the fruit quality i.e., physical fruit quality TSS and vitamin C were enhanced. The promising combination was 50% from the recommended NPK plus 20 m2 dried biogas digester residual organic fertilizer, which gave the best values of plant growth and yield, also fruit characters were enhance.Concerning the economical evaluation, adding the 50% of recommended NPK combined with 20 m2 dried biogas digester residual organic fertilizer led to obtain the highest total yield of pepper plants as well as total revenue as compared with the other treatments under this investigation.

Field Experiment was carried out in summer seasons of 2014 and 2015 at the Experimental Farm of Rice Research Section, El-Gemmiza, Agricultural Research station, El-Gemmiza, Gharbia Governorate, Egypt. This fulfillment was conducted to study the response of three rice genotypes (Sakha 106, Giza 179 and Hybrid 3), two types of fertilization (chemical and compost fertilization), weeding control (hand weeding and chemical control) and plant density (one, two and three plants/hill) on yield and its attributes traits. Genotypes significantly differed in all studied traits. Hybrid 3 genotype produced the maximum values of No. of tillers and panicles/m², length of panicle , No. of total grains for panicle and 1000- grain weight as well as yield of grain/fed). While, the lowest values of these traits were recorded with Sakha 106 genotype. Chemical fertilization had significant effect on some of studied charactars. Weeding control treatments had non-significant effects on all studied characters, except No. of tillers/m² and length of panicle in the 1st season. Three plants/hill produced the highest values, while the lowest values of the previous traits were obtained when using one plant/hill. In general, it could be recommended that planting Hybrid 3 genotype as one plant/hill, Giza 179 genotype as two plants/hill and sakha 106 genotype as three plants/hill and organic fertilized with compost and using hand weeding under the new treatments of system of rice intensification.

Two investigations were carried out in the open field to study the effects of some soil stimulating supplements, i.e., humic and fulvic acids, zeolite, chicken manure as well as compost on vegetative growth, chemical contents and productivity of sweet pepper plants under drip irrigation system. Results indicated that all applied soil substances significantly enhanced vegetative growth parameters, chemical constituents, endogenous phyto-hormones of leaves, yield and fruit quality compared to the control in both growing seasons of study. Soil applications of either zeolite or compost are the best treatments in enhancing most of the aforementioned parameters. Additionally, our results undoubtedly confirm that the application of zeolite or compost could decrease chemical fertilizers through improving the efficiency of both fertilizers and irrigation water which in turn increase vegetable crops production, minimize economic costs as well as limit environmental contamination.

Effect of Sowing Dates, Irrigation Intervals and Organic Fertilizers on Growth and Productivity of Pea Plants (Pisum sativum L.) under Sandy Soil Conditions
Two field experiments were conducted during winter seasons of 2014-15 and 2015-16 at the Agric. Res. Station, Veg. Res. Dept., Hort. Res. Inst., Agric. Res. Center, in El- Arish, North Sinai Governorate, Egypt. The aim of this investigation to study the effect of two sowing dates (15th October., and 15th November), two irrigation treatments (100% for water requirements for pea , which is 2100 m3 distributed through the growth stage to irrigation every day and irrigated every two days by half of these requirements) and five fertilization treatments (100% NPK from recommended dose as control, Cow manure, and Compost at rates of 10 and 20 m3 per fed. from each) on Sementi Pea (Pisum sativum L.) cultivar growth and yield under sandy soil condition with drip irrigation system. The treatments were arranged randomly in a split-split -plot design, in three replications where the two sowing dates were randomly arranged in the main plots, two irrigation intervals were randomly distributed in sub plots., and five fertilization treatments were allotted in sub sub plots. The results showed that the highest values of all growth parameters; i.e., plant height, number of branches, number of leaves as well as the fresh and dry weight of pea plants, recorded at the first sowing date (15th October) and irrigation every day with addition of compost at the rate of 20 m3 or 10 m3 per fed. Followed by sowing in the same date and the irrigation every two days with addition of compost at the rate of 20 m3 per fed. The results indicated that the first sowing date (15th October) of pea plants with irrigation every day or every two days and adding organic fertilizer from compost at the rate of 20 m3 per fed recorded the highest values of number of pods per plant, number of seeds per pod, pod length, and yield per plant as well as total yield per fed. Followed by planting in the same date with irrigation every day and adding of compost fertilization at the rate of 10 m3 per fed. Also, the results showed that the highest values for leaf content of photosynthetic pigments as well as the seed content of N P K and protein were obtained from sowing on 15th October and irrigation each day with adding compost fertilizer at the rate of 20 and 10 m3/ fed. Followed by sowing on the same date with irrigation every two days and adding 20 m3 of compost /fed. Regard to the water relations, resulted indicated that, irrigation of pea plants every two days during the different stages of growth reduced the total yield by 17.29 - 17.06 % , and saving about 2.86 - 3.09 % of (IWR) in the two growing seasons, respectively. In addition, increasing all investigated organic fertilizer rates with lowering of amount water irrigation led to water saving more than 24%. Among these results, it is clear that the highest value of water use efficiency (5.96 and 6.40 kg/m-3) in the first and second season, respectively was obtained with application of the doubled amount compost ( 20 m3 per fed.) with irrigation every two days under sandy soil condition in North Sinai location.

Two field experiments were conducted during late summer seasons of 2015-2016 at the Agric. Res. Station, Veg. Res. Dept., Hort. Res. Inst., Agric. Res. Center, in El- Arish, North Sinai Governorate, Egypt. The aim of this work was to study the effect of three tomato hybrids (Lycopersicon esculentum Mill.); i.e. one local "Eyeon" hybrid as well as two foreign hybrid (Alisa and GS-12) and two sources of organic fertilization each at 120 and 150 Kg N fed-1 (Chicken manure "ChM" and Cow manure) under sandy soil condition and high saline water with drip irrigation system. The treatments were arranged randomly in a split-plot design arrangement in randomized complete block design, in three replications where the three tomato hybrids were randomly arranged in the main plots, the two sources of organic fertilization were randomly distributed in sub plots. The results showed that, all growth parameters, (roots, leaves, and stems, as well as clusters fresh weight and both total fresh and dry weight) gave the highest values under "Eyeon" hybrid plantation and application of high rate (150 Kg N fed-1) from ChM followed by "GS-12" with the same of fertilization treatment. Yield and its components for early and total yield results showed that planting of local "Eyeon" hybrid with application the high rate of 150 kg Nfed-1 from ChM recorded the best values for yield characters i.e., number of fruits and fruit weight for grades A and B (g plant-1 and ton fed-1) as well as early and total yield for grade (A+B ton fed-1.) compared to other treatments, in both seasons. Regarding to the fruit quality, the obtained results showed that fertilization of local "Eyeon" hybrid by ChM at the rate of 150 Kg N fed-1 recorded the highest values for pH, V.C, T.S.S in tomato fruit juice as well as fruit firmness and dry matter content in tomato fruits. The Local "Eyeon" hybrid was more responses to the high rate (150 Kg N fed-1 from ChM). For that it can recommend by cultivation the local "Eyeon" hybrid in North Sinai which it was more superior for produce high fruit yield with best quality when fertilized with chicken manure at the rate of 150 Kg N fed-1 under the condition of saline water irrigation compared with using the foreign tomato hybrids either Alisa or GS-12 which it is import from abroad.

Estimation of Combining Ability and Hetrosis Via Half Diallel Cross in Faba Bean (Vicia faba L.) for Yield, its Components and Seed Quality.
This investigation was carried out at Sakha Agricultural Research Station Farm, Kafr El-Sheikh, Egypt. Seven faba bean (Vicia faba L) cultivars and/ or varieties were used as parents, sown and crossed with each of half diallel set giving a total of 21 crosses under insect free cages. The resulted F1,s along with their parental genotypes were sown in a complete randomized block design with three replications during 2016 /17 season. Griffing approach (1956) was used to estimate general and specific combining ability effects. The results pointed out that additive and non-additive nature of gene action were involved in controlling the inheritance of all studied traits. The ratio of GCA/SCA mean squares was higher than unity for flowering date, number of branches/plant , 100-seed weight and EC of seeds, while the same ratio was less than unity for plant height, number of pods/plant , number of seeds/plant, seed yield /plant and protein percentage. The parental varieties; Giza40 and Line1 considered as good source for yield improvement, while the parental varieties; Giza 429 and Maghreby1 considered as good combiners for improvement of earliness and yielding ability. The crosses; Ohishima-Zaira x Giza40, Ohishima-Zaira x Line1, T.W x Line1, Line 1x Sakha1 and Sakha1x Maghreby1 expressed highly significant inter and intra-allilic interactions in desirable direction for the traits in view. The crosses; Ohishima-Zaira x Giza40, Giza429 x Giza40, T.W x Ohishima - Zairai, T.W x L1 and T.W x Maghreby1 exposed significant better parent heterosis for most studied traits. Progenies of these crosses could be used in the segregating generations with application of bulk method to regenerate pure line(s) characterized by high yielding potentiality and high protein content.

Spraying Seaweed Extract and Hand Trimming to Improved Yield and Fruit Quality of Grand Nain Banana Plants
This experiment was carried out during 2013- 2014 (first ratoon) and 2014-2015 (second ratoon) seasons to study the effect of spraying seaweed extract at three concentration 0, 0.1, 0.2 % and/or trimming (without one & two hand) on Grand Nain banana bunches in sandy soil. Trimming of hands was done after bunch shooting, seaweed extract sprayed three times: 1) after bunch shooting directly, 2) 15 days later 3) 30 days later. Time to harvesting, bunch weight (kg), estimated yield (ton), estimated increasing rate of yield (%), finger diameter (cm), finger weight (g) finger length (cm), soluble solids content (SSC) and titratable acidity percentage were determined. Obtained results showed that trimming with two hands gave the highest values for the above mentioned characters compared with one hand. Time of harvesting tended to decrease with hand trimming of banana. The highest values of bunch weight, yield, increasing rate of yield and finger parameters were obtained from Grand Nain banana plants trimming two hands with spraying seaweed extract at 2 % .Seaweed (Ascophyllu mnodosum L.) is a known source of plant growth regulators which an important roles in metabolism and productivity of plants. Moreover, hand trimming is practiced to increase the finger parameters. From the obtained results it could be concluded that, spraying seaweed extract at 2% with trimming two hands improved time to harvesting, yield as well as physical and chemical characteristics of the fruits of Grand Nain banana plants. A superior effect was attributed to using seaweed extract and trimming rather than control.

Effect of Organic Nutritional Supplement on Growth, Nodulation and Yield of Peanut Cultivated Under Different Fertilization Systems
In order to study the effect of fertilization systems (100 % NPK, 100 % compost, 50 % compost + 500 kg mineral ores mixture and 50 % compost + 500 kg gypsum) as soil application and organic substances (control, KP, KSi and CT) as foliar application on growth performance, chlorophyll content, nodulation and yield of peanut (Arachis hypogaea L., Giza 6 cv.). Two field experiments were carried out in extension field at Quweisna, Menoufia governorate, Egypt during the two growing seasons of 2015 and 2016. Results indicated that adding fertilization systems and organic substances generally had effective roles on enhancement of growth and yield of peanut grown in sandy loam soil. Application of 50 % compost + mineral ores mixture produced the highest growth characters i.e number of main branches and leaves /plant, stem and leaves dry weight/plant and leaf area/plant . However, application of 100 % compost exhibited more total chlorophyll content, number and nodules weight/plant, yield and its components (number of pods/ plant, number of seeds / pod, weight of seed /plant and pod yield per plant and per fed and seed oil percentage compared with other tested fertilization treatments. The response of peanut Chlorophyll and nodulation, yield and oil percentage significantly differed by foliar application of organic substances. Application of Jeta Plus (KP) and Si-ElGhanem (KSi ) surpassed the other organic substances for producing highest values of most above mentioned characteristics. However, untreated plants recorded the lowest values of all studied characteristics. The interactions between the fertilization systems and organic substances were found to be significant for most studied traits. The maximum pod yield/fed was obtained by soil application of 100 % compost combined with foliar application with KP, which is found to be the best combination for maximizing peanut productivity. Accordingly, the study recommends the importance of regular use of organic fertilization as soil or foliar application to reduce the need for synthetic commercial fertilizers and reduced soil pollutions.

Genetic Analysis of Yield and Its Components in Some Bread Wheat Crosses (Triticum aestivum L.) using Five Parameters Model.
The present investigation was done at the Experimental Farm of Agronomy Department – Faculty of Agriculture Al-Azhar University, Nasr City, Cairo, Egypt during four successive seasons from 2012/2013 to 2015/2016. Four bread wheat varieties (parents) Misr1, Gemmeiza 9, Gemmeiza 10 and Gemmeiza 11 were chosen to form three bread wheat crosses; Misr 1× Gemmeiza 10, Gemmeiza 9× Gemmeiza 11 and Gemmeiza10×Gemmeiza 11. Five parameters model was used for measuring some important genetic parameters for yield and its component characters. These characters were number of spikes / plant, spike length (cm), grain weight/spike (gm), number of grains / spike, 100- grain weight (gm), grain yield / plant (gm) and harvest index %.Randomized complete block design (RCBD) with three replicates was used in the final experiment. Five populations (P1, P2, F1, F2 and F3) for each cross were used in this investigation. Results revealed that, the F1 population recorded the highest mean values compared with other populations for all characters in the three crosses except grain weight/spike in the third cross .The data also showed that, standard error estimates in F2 were larger than other populations. All studied traits in this investigation were controlled by both additive and non-additive genetic effects, but the values of dominance × dominance epistatic gene effects were greater than the other effects for most traits. Estimates of heterosis relative to mid-parent were positive and significant for number of spikes / plant, spike length, number of grains / spike and grain yield per plant in all crosses under study, while, the estimates of heterosis relative to better parent were positive and significant for number of spikes /plant and grain yield / plant in all crosses. Inbreeding depression percentage from F1 to F2 and F3 were positive and significant for most studied characters. potence ratio revealed over dominance for most studied traits. Heritability in broad sense found to be moderate to high in most traits in three crosses, these estimates ranged from 0.56 for spike length in the second cross to 0 .84 for 100- grain weight in cross 2, while the values of narrow sense heritability were low to moderate for all studied characters in the three crosses, these values were between 0.01 for number of spikes/plant in the second cross and 0.56 for number of grains/spike in the first cross.

Micropropagation of thyme plant (Thymus vulgaris)
The current research was conducted at Vegetable and Floriculture Department in the experimental station and tissue culture laboratory, Agriculture Faculty, Mansoura University. The objective of this research was to develop a direct plant regeneration of a valuable aromatic and medicinal plant (Thymus vulgaris) by in vitro culture of shoot tips or nodal segments from mature plants on MS medium supplemented with different cytokinin type at different concentrations. Nodal segments were found to be more efficient than shoot tips for Thymus vulgaris shoots regeneration on MS medium (Murashig and Skoog 1962) supplemented with 6-benzyladenine (BA) at 2 mg/L. The best elongation was obtained on MS medium supplemented with BA at 2 mg/L in combination with GA3 at 0.5 mg/L.The best rooting of shoots was obtained on MS medium augmented with α-naphthaleneacetic acid (NAA) at 1.5 mg/L. Regenerated plants were successfully established in pots filled with mixture of soil: peat moss (1: 1 v/v). In vitro Thymus vulgaris plants had a survival rate of 100 %, and showed healthy and uniform growth.

Effect of Foliar Application of some Plant Extracts and Amino Acids on "Picual" Olive Production and Oil Quality
The experiment was carried out during 2015 and 2016 seasons on 20 years old Picual olive trees and grown in a sandy soil at experimental Farm of Faculty of Environmental Agricultural Sciences, Arish University, North Sinai Governorate, Egypt, to examine the effects of aqueous extracts of Athir (Artemisia monosperma),Moringa (Moringa oleifera) and Kabbar (Capparis spinosa) at four concentrations (0, 5, 15, and 25%) with Protamine (the commercial form of amino acids mixture) at 1.5 % on growth, leaf nutrient contents, productivity, fruit quality and oil properties of "Picual" olive trees. Fresh leaves were collected, washed with tap water, chopped and pounded, soaked in distilled water and filtered to prepare extracts at 5,15 and 25%. Plant extracts were sprayed three times at 70% full-bloom, after fruit set, and a month later. A control experiment with distilled water was also set up. Treated olive trees were arranged as a factorial experiment in a randomized complete block design with three replicates, each replicate was represented by two trees. The obtained results indicated that, most plant extracts with amino acid treatments significantly increases vegetative growth (shoot length, number of leaves, leaf area, leaf pigment contents, leaf chemical constituents), fruit yield, fruit physical and chemical properties, as well as oil production compared with the control. Treatments with A. monosperma or M. oleifera at 25% with/out 1.5% amino acid (Protamine) were the most effective ones compared with the other treatments.

Indirect Micropropagation of Thymus vulgaris Plant.
A protocol for indirect micro propagation of Thymus vulgaris was developed using shoots tips explants derived from ex vitro mother plants. Murashige and Skoog (MS) Medium with different concentrations of auxins (NAA, IAA and 2,4-D) alone or in combination with different cytokinins (BA and Kin) were used to induce callus formation. MS medium supplemented with 2,4-D at 2 mg/L in combination with Kin at 1 mg/L produced the highest callus formation percentage of 100 % and significantly counted spectacularly callus fresh weight of 9.56 g. The highest Callus regeneration percentage (100 %) commitment to the highest significant shoots number (23.42 shoots/ explant) were obtained on MS medium provided with BA at 2.5 mg/L. The preferable rooting of shoots was obtained on MS medium half strength augmented with 30 g/L sucrose and NAA at 1.5 mg/L. On this medium, 100 % of the shoots produced roots with a mean number of 19.83 roots per shoot. Shoots with well-developed roots were successfully established in pots filled with mixture of soil: peat moss (1: 1 v/v). The survived plantlets had a survival rate of 98 %.

Effect of Plant Compost Enriched with Spirulina Platensis Algae as a Partial Replacement of Mineral N Fertilizers on Early Sweet Grapevine
During 2014 and 2015 seasons, Early Sweet grapevines were fertilized with the recommended rate of N via 100% mineral N, 100% plant compost (p c) enriched or not with Spirulina platensis algae(S p a) as well as via 25 to 75% inorganic N plus 25 to 75% plant compost with or without Spirulina platensis algae. The merit was replacing inorganic N partially by using plant compost enriched or not with Spirulina platensis algae. Growth characteristics, leaf pigments, N, P, and K, yield, quality of the berries and juice content of nitrite were investigated. Using N as 50% inorganic N + 50% plant compost enriched with Spirulina platensis at 10 ml/ vine improved growth characteristics, yield, cluster weight and quality of the berries. There was a gradual effect on leaf pigments, N, P, K and fruit quality with reducing the percentages of inorganic N from 100 to 0.0% and increasing percentages of plant compost with or without the algae form 0.0 to 100%. Juice content of nitrite and shot berries % gradually declined with reducing inorganic N and increasing plant compost enriched or not with Spirulina platensis algae. Using plant compost enriched with Spirulina platensis was more favorable than using plant compost alone in this respect. A pronounced promotion on yield and fruit quality of Early Sweet cultivar was observed when the vines were subjected to the recommended rate of N as 50% inorganic N plus 50% plant compost enriched with Spirulina platensis algae at 10 ml/ vine.

The field experiment was carried out during two successive summer seasons of 2014 and 2015 at the agricultural experimental station of Khamisa, Desert Research Center Siwa Oasis, to study the response of three sunflower varieties, i.e. Hysun333, Sakha 53 and Giza 102 to foliar application by natural compounds chitoker. Seven natural compound treatments which used were , 1- without natural compound (as control), 2-spraying by 150 ml./100 liters in the vegetative growth stage, 3- spraying by 150 ml./100 liters in the vegetative and syphilis growth stages. 4- Spraying by 200 ml./100 liters in the vegetative growth stage, 5- spraying by 200 ml./100 liters in the vegetative. 6- Spraying by 250 ml./100 liters twice in the vegetative growth stage, and, 7- spraying by 250 ml./100 liters twice in the vegetative and syphilis growth stages.The obtained results could be summarized as follows:Sunflower verities were differed significantly in yield and its components, oil contents and oil yield. Giza 102 variety was superior to Hay Sun 333 and Sakha 53 varieties.A significant difference between the parameters of the natural compounds as chitoker, where the spraying twice by chitoker at 250 ml./100 liters of during the vegetable and flowering stages had a significant increase as compared to the rest of the treatments. All studied traits were significantly affected by the interaction between varieties and spraying by different chitoker treatments. An general, sprayed Giza 102 variety twice by the natural Chitoker at 250 ml. / 100 L. rate during vegetative and pre- flowering stages produced the highest yield, yield components and oil yield.The results of the calculation of the economic yield of the crop showed that the cultivation of the sunflower crop in Giza 102 + spraying with the natural compound Chitoker rate of 250 ml./100 liters of water in two stages are spraying in the stage of vegetable growth and spray in pre-growth flowering Is the best experimental economic transaction for the farmer, With some other factors being given an economic rate but to a lesser degree. This study concluded that the cultivation of Giza 102 sunflower variety + spraying twice with the natural compound Chitoker rate of 250 ml./100 liters of water in two stages of vegetable and pre-growth of the Zahra under the conditions of Siwa Oasis gave the best results economically.

Response of Red Globe Grapevines to Spraying Barley Seed Sprout and Silicon
The effects of spraying barley seed sprout and/ or potassium silicate each at 0.025 to 0.1% on fruiting of Red Globe grapevines was examine during 2015 and 2016 seasons. The selected vines were sprayed three times with such two stimulants. Barley seed sprout and potassium silicate each at 0.025 to 0.1% single and combined applications improved growth aspects, leaf pigments, some nutrients, berry setting %, yield and fruit quality compared to the control treatment. Using combined applications was superior to using each alone.The effect on these parameters depended on increasing concentrations. Spraying a mixture of barley seed sprout and potassium silicate three times each at 0.05% improved yield and quality of Red Globe grapevines under Minia conditions.

Effect of Irrigation and Potassium Fertilizer on Vegetative Growth, Yield and Quality of Globe Artichoke Plants under Sandy Soil Conditions
A field experiment was carried out during 2014/2015 and 2015/2016 seasons at El-Kassasin Horticulture Research Station, Ismailia governorate, Egypt, to study the effect of irrigation and potassium fertilizer treatments on vegetative growth, yield and quality of globe artichoke plants under drip irrigation system in sandy soil. The experiment was designed as split plot. Main plots devoted to irrigation treatments which included irrigation with 100% of ETc (I1), 80% of ETc (I2) and 60% of ETc (I3). While potassium fertilizer treatments were in the sub-plot. Potassium fertilizer treatments were 100% of recommended potassium fertilizer dose (K1), application of 75% and 50% from recommended potassium fertilizer dose plus 1% foliar potassium citrate (K2 and K3 respectively). Results indicated that the highest values of plant height, leaf fresh and dry weight, number of offshoots plant-1, flower heads fresh weight and diameter, fresh weight and diameter as well as thickness of receptacle, number of early and total flower heads plant-1 and total yield fed-1 were obtained from I1 and K1, while the lowest values resulted from I3 and K3. There were no significant differences between K1 and K2 potassium treatments for all characteristics, as well as between I1× K1 and I1× K2 interactions in the two growing seasons. Seasonal applied water was 39.32, 31.63 and 23.97 cm when globe artichoke plants were irrigated with 100, 80 and 60% of ETc respectively. The highest values of productivity of irrigation water (PIW) resulted from irrigation with 60% of ETc. At the same time, potassium treatments of K1 and K2 not only resulted in higher yield but also increased the PIW. Generally, it could be concluded that under study condition irrigation with 100 ETc and application of 75% from recommended potassium fertilizer dose plus 1% foliar potassium citrate was the best combination for globe artichoke yield and its quality. When water becomes limiting factor, the treatment of I3 x K2 could be recommended.
